1000/1150 kVA Distribution Transformer Substation-13.8/0.48 kV|USA 2025

01 General

1.1 Project Description

1000/1150 kVA substation transformer tau xa mus rau Asmeskas hauv xyoo 2025. Lub zog ntsuas ntawm lub transformer yog 1000/1150 kVA nrog KNAN / KNAF txias. Thawj qhov hluav taws xob yog 13.8 kV nrog ± 2 * 2.5% tapping ntau yam (NLTC), qhov nruab nrab voltage yog 0.48GrdY / 0.277 kV, lawv tsim ib pawg vector ntawm Dyn1.

Lub 2000/2300 kVA substation transformer yog tsim los xa cov khoom siv hluav taws xob txhim khu kev qha thiab muaj txiaj ntsig zoo rau Junction House - 1. Lub tshuab hloov pauv tau ntim nrog FR3® dielectric kua, muaj kev ruaj khov thiab siab -cov roj insulating ua tau zoo uas txhim kho thermal stability, ncua cov khoom siv lifespan, thiab muab kev nyab xeeb ib puag ncig zoo dua piv rau cov roj ntxhia hauv cov pa.

Ib qho tseem ceeb ntawm kev nyab xeeb ntawm qhov system no yog 5-amp nruab nrab grounding resistor (NGR), uas txwv tsis pub tam sim no thiab tiv thaiv lub transformer los ntawm kev puas tsuaj thaum lub sij hawm hauv av txhaum. NGR tau saib xyuas los ntawm 5: 5 piv tam sim no transformer (CT) nrog C10 qhov ntsuas qhov tseeb, kom ntseeg tau qhov tseeb qhov txhaum thiab kev tiv thaiv kab ke.

Engineered rau durability thiab ua raws li cov qauv kev lag luam, qhov transformer no ua kom ruaj khov xa hluav taws xob thaum tseem ceeb ntawm kev nyab xeeb, kev ruaj khov, thiab kev ua haujlwm zoo rau Junction House - 1.

02 Kev tsim khoom

2.1 Core

Lub hauv paus ntawm peb-theem, peb-limb substation transformer feem ntau yog tsim los siv cov ntawv laminated silicon steel los txo qhov poob tam sim no thiab xyuas kom muaj kev sib nqus zoo. Cov qauv tsim no muaj peb ceg ntsug sib txuas los ntawm cov yokes sab sauv thiab qis, muab txoj hauv kev sib nqus sib npaug rau peb -theem flux. The stacked-lamination technique enhances mechanical stability, reduces no-load losses, and improves overall transformer performance. Nws cov qauv ruaj khov thiab kev cog lus ua rau nws zoo tagnrho rau siab - lub zog xa hluav taws xob thiab kev faib khoom siv.

2.2 Cua txias

LV Winding:Ua los ntawm cov ntawv ci tooj liab, nruj txheej txheej nrog interlayer rwb thaiv tsev, muab luv luv - lub zog hluav taws xob thiab kev ua haujlwm thermal.

HV Winding:Tsim los nrog insulated tooj liab hlau nyob rau hauv txheej - hom tsim, ua kom ntseeg tau tig- mus rau - tig rwb thaiv tsev rau siab -voltage endurance thiab mechanical stability.

2.3 Tank

Lub tank ua hauj lwm raws li kev tiv thaiv enclosure, fabricated nrog tag nrho cov welded corrugated steel los yog ntxiv zog panels los xyuas kom meej cov qauv kev ncaj ncees thaum maximizing tshav kub dissipation. Nws nto undergoes sandblasting thiab multi- txheej tiv thaiv -corrosion txheej rau ntev - lub sij hawm sab nraum zoov durability. Sau nrog qib siab -cov roj insulating, lub tank muab ob qho tib si hluav taws xob rwb thaiv tsev thiab ua kom txias txias los ntawm cov roj ncig. Lub tank sib dhos muaj xws li bushings, roj kub / qib ntsuas, cov cuab yeej siv siab, thiab Buchholz relay. Sab phab ntsa integrates tshem tau cov radiators, nrog rau cov dej ntws thiab cov chaw nres nkoj hauv qab, tsim kom muaj kev tiv thaiv, txias, thiab saib xyuas.

2.4 Kev sib dhos zaum kawg

Kev sib dhos zaum kawg ua ke nrog cov tub ntxhais, HV / LV windings, thiab cov txheej txheem rwb thaiv tsev rau hauv lub tank corrugated tom qab lub tshuab nqus tsev ziab thiab roj filling. Cov khoom tseem ceeb xws li bushings, cua txias, kev tiv thaiv relays, thiab kev saib xyuas cov tshuab raug teeb tsa, ua raws li kev ntsuam xyuas hermetic thiab tag nrho cov kev ntsuam xyuas niaj hnub los txheeb xyuas cov neeg kho tshuab kev ncaj ncees, hluav taws xob kev ua tau zoo, thiab kev cia siab rau kev ua haujlwm raws li cov qauv.

03 Kev Xeem

04 Packing thiab Shipping

4.1 Ntim

Lub tshuab hluav taws xob hluav taws xob hloov pauv tau ntim nrog cov hlau- ntoo hybrid qauv, qhwv nrog cov yeeb yaj kiab los tiv thaiv- xeb thiab cushioned nrog kev poob siab- cov ntaub ntawv nqus. Cov hlua hlau txhawb nqa sab nrauv, nrog cov cim nqa thiab ya raws- cov ntawv pov thawj los tiv thaiv kev puas tsuaj thiab ib puag ncig corrosion thaum thauj.

4.2 Shipping

Lub substation transformer yog thawj zaug thauj los ntawm hnyav- tsheb thauj mus los rau qhov chaw nres nkoj, nrog cov cuab yeej tshwj xeeb ruaj ntseg kom ruaj ntseg. Thaum tuaj txog lub thawv shipping chaw nres nkoj, nws yog loaded rau hauv ib lub thawv los yog ca racking, ntxiv dag zog rau, thiab kho rau kev tiv thaiv ya raws ua ntej yuav raug xa los ntawm lub thawv ntim. Thaum lub sijhawm thauj mus los, lub thawv ntim tau ruaj ntseg ntawm lub lawj lossis hauv qhov tuav, nrog rau qhov tiag -lub sijhawm saib xyuas qhov kub, av noo, thiab kev vibrations kom lav kev xa khoom nyab xeeb ntawm qhov chaw nres nkoj.

05 Site thiab Summary

Raws li lub hauv paus ntawm lub tshuab hluav taws xob, peb lub tshuab hluav taws xob substation sawv tawm rau kev ntseeg tau zoo dua, kev ua haujlwm siab, thiab kev ua neej ntev, ua kom muaj zog ruaj khov thoob ntiaj teb. Nrog rau kev txiav- thev naus laus zis thiab kev tswj xyuas kom zoo, peb xa cov kev daws teeb meem kom tau raws li cov kev xav tau sib txawv. Kev xaiv peb cov khoom txhais tau hais tias muaj kev nyab xeeb, kev ua tau zoo, thiab lub zog muaj zog yav tom ntej.
